When the wearable device works in a measurement mode, the LED module can control the LED unit to emit light after receiving a measurement instruction, and health data of a user are collected. After the wearable device receives a triggering operation performed by a user, the operating mode of the LED module may be switched from the measurement mode to the communication mode, so that the LED module may establish an optical communication connection with the external device.

After the wearable device determines that the LED module of the wearable device is aligned with the external device, the wearable device can establish optical communication connection with the external device by adopting the LED module, so that the wearable device can exchange data with the external device through the optical communication connection; furthermore, since the LED module is a health measurement module on the wearable device, the wearable device can perform optical communication connection by multiplexing the LED module for implementing the health measurement function, so that the wearable device can implement the near field communication function without adding other near field communication modules, which can reduce the cost of the wearable device and the volume of the wearable device; for wearable equipment with other near field communication modules, the communication method of the wearable equipment can enrich the connection mode of communication connection between the wearable equipment and external equipment on the basis of not increasing the cost, so that the man-machine interaction of the wearable equipment is more intelligent.
In one embodiment, on the basis of the above embodiments, after the wearable device receives the trigger operation of the user on the wearable device, the connection prompt information may be further output to the user in response to the trigger operation of the user on the wearable device.

The connection prompt message may include a simulated user action of turning over the watch body, and the user may turn over the watch body according to the connection prompt message, so that the light emitting surface of the LED module at the bottom of the turned over watch body may face the external device.
According to the communication method of the wearable device, the wearable device outputs the connection prompt information to the user, so that the user can more accurately and effectively align the LED module with the external device according to the connection prompt information, the alignment time is shortened, and the optical communication connection efficiency is improved; in addition, the user of the wearable device can more intuitively finish the alignment operation according to the connection prompt information, the user is prevented from trying to align for multiple times under the condition of uncertain operation steps, and the intelligence of man-machine interaction is improved.
